This'invention relates to detachable cardholders to facilitate thetyping of short, stiff.

cards in typewriting machines. y i

Heretofore, when it was desired to use a standard machine for specialcard-writing, it l wasV necessary to change theordinary platen to onehaving pins fixed thereon, requiring the skillv of a mechanic to makethe chantre, .and being Vinconvenient and costly. The platen had to beprovided with pins protruding from one end, for lengaging a rigidstop-arm on the carriage, so that by'rneans of a card-holder, the pins,and-the stop-arm, the cards could be quickly inserted and brought toprinting position. o It is desired to render the machine suitable foreither card-writing or for ordinary work. j A feature of thisvinventionis the provision of a card-holding attachment which may beeasily attached to and detached fromy any standard typewriter. For thispurpose the pins areconstructed'integral*with the cardholder, so that,by attaching or detaching'the card-holder, the pins will besimultaneously placed on or removed from the machine. o

Another feature of the invention is the provision of a permanentstopfarm, normally held inthe path of the pins but swingable out oftheir path, for allowing the card-holder to be turned to a position forremoving it from the machine.

Still another feature of the invention is the provision of means on the'card-holder for pre- Yventing a pair of tongues formed' in the cardfrom catching upon the inl: ribbon or the wing-scales, comprising anextension on the card-holder to cover `the tongues7` thereby holdingthem close to the platenand `preventing them from contacting with.y any'other part'sof the typewriter. y

"Other features and dvantages will hereinafter appear. l

Referring to the drawings aplaten ,10v is revolubly mounted on av shaft111 journaled in end plates 12 and* 13 of a carriage frame 14C. Theplaten may be rotated Iby a hand wheel 15 mounted on the shaft 11 orbyline-spacing mechanism not shown.

lin order to facilitate the writingof short stiff cards 16, acard-holder 17 is provided. The card-holder consists of a thin metal bar1S extending 4the length of the platen and curved to conform closelywith theperiphery Aof the platen. The bar' .1S terminates in forkedportions 19 and 2i() bent down at right angles, and which, when placedonthe mar chine, straddle flat portions 21, on the platenshaft 11,adjacent the ends of the platen, so that, as the'pl'aten is rotated, thecard-holder will be carried therewith. For holding the bar l8tightlyagainst the platen a hook meni-` loer 22 is pivotally mountedatZS toeach of the 'forked' portions or plates 19 and 20 and may be lswungabout its pivot by means of a handle 24: t-o lengage the portion 21 andhold thecardholder ink place. The hook member isheld in to a pin 26vOnthe hookrnember and at its other end toa pin 27 lon the forkedportion. rlhe card-holder hasan under cut 2,8 Vagainst foperativeorinoperative position means of Y a double acting spring 25 attached atoneen d which the v'bottom redge of the card 16.l is aligned and aprojecting finger 29 for `aligning the sideedges of the cards.

To prevent these tonguesfroin catchingon any parts of the machine suchas the ribbon 31 or wing-scalesBQ, thecard-holder 17 is pro-4 therebypreventing vthem from protrudingy e5 vided 'with van extension .33.

position. v After having completed the typing on the` Oard,"the VplatenAis again rotated tok i bring the card and card-holder to a position'Where the typed card can be removed and a fresh one inserted.

Av`For vrendering the'platen quickly rotat-- able to either typing orcard-inserting posi-V tion ai pair of positioning members is provided.These members or arresting means Vare in the form of pins and 36 rigidlysiredto use the machine for ordinary Work the platen is rotated toFigure position and byl releasing the hook members 22 the card-holder17, with the pins 35 and 36, can be liftedofla the platen 10. ln orderto turn the platen to Figure 4 position,'the pins must Abe'able' to passby the stop 37. For this purpose the stop 37 on the arm 37a is swing'-ably mounted on a pin or stud 39 carried by a pair of ears 40 of thebracket 38. The stop 37 is normally held in the path of the pins orarresting means 35 and 36 by means of a spring Ll1 on the stud 39, butmay be swung out of their path by operation of a lingerpiece'etQ on theupper end of the arm 37a, For preventing the spring 4:1 from swingingthestop 37l too close to :the platen and into the path of the handle 2lion the hook member 22, the arm 37 has its upper portion 43 bentoutwardly to abut against the bracket 33 and thereby limit the arm andthe stop in their movement towards the platen.

The pin 35 acts as a limiting stop `for the hook member 22 when' thelatter is moved to its ineffective position.y

Variations may be resorted to Within the scope of the invention, andportions of the improvements may be used Without others.
